HS-SR04 Wires are twisted change ECHO <-> TRIG #35

Hey, I've uploaded your firmware to Wemos D1 mini and no matter how I define pins I'm getting message "HS-SR04 Wires are twisted change ECHO <-> TRIG" on console output. Any idea?

Thanks and regards, Przemek.

The model requires 5V on VCC. Please double check you have the voltage at the sensor

I know the reason for this info but not sure if it should work that way. This message appears also when sensor is not perpendicular to surface..

SR04 is now part of the official Tasmota project. Changed all sources to the main branch. Any issues must now we fixed there.
